Abstract
A crash cushion system to envelop at least one bridge pier. The system has two impact heads, one facing one traffic flow direction and the other facing an opposite traffic flow direction. The heads are connected to multi-stage box beam energy absorbers which are in turn connected to a tubular frame structure which envelops the bridge piers. The frame is spaced apart from the face of the pier sufficiently to avoid an impacting vehicle's snagging the frame and contacting the pier structure. Anchorage cables to stiffen and support the sides of the envelope are positioned inside the frame's parallelogram shape.
